Abstract

Miocene rhyolitic shallow intrusions, cryptodomes and domes emplaced into soft, wet sediment in shallow subaqueous environment form a large intrusive complex in the NE side of the Tokaj Mts. at Pálháza in NE-Hungary. The intrusive complex show interaction textures with the host sediment where blocky peperites formed in a dm-scale, however, irregular contacts closely resembling globular mega-peperites are prominent in the tens of metres scale. The more than 200 m thick succession of intrusive complex interpreted to be a generally steadily growing shallow dyke, cryptodome, and dome complex in a shallow subaqueous environment, similar to those reported from Ponza, Italy.
